Abstract: PURPOSE:To carry out smooth vaporization of the methanol-water mixture and to promote reformation of the vaporized gas, by providing a part of the path for feeding the methanol-water mixture as a preheater on the outer wall of the vessel. CONSTITUTION:The methanol reformer including the combustion zone 4 and the reformation zone 5 is provided, on the outer wall 12 of the vessel, with a preheating path 13 constituting a part of the path for feeding the methanol- water mixture to the reformation zone 5. The methanol-water mixture is fed by pump 3 from the tank 1, and heated, while it passes through the preheating path 13 in the annular chamber, with the heat from the combustion zone 4, then fed through the outlet 16 into the reformation zone 5. When the temperature of the mixture (the outer temperature) is -20 deg.C, the outlet temperature of the preheater 13 rises up to about 60 deg.C and the mixture is rapidly vaporized in the evaporator of the reformer 5. The vapor is reformed, while it passes through the catalyst 1.

IPC: B32B37/10
Filed: 1986-09-25
Abstract: PURPOSE:To prevent generation of jams by reducing an installation space, by a method wherein the title equipment possesses a pair of hot press rollers and a pair of feed rollers of a thing to be treated and is provided with a sensor detecting a position of the thing to be treated and a control device making peripheral speeds of respective rollers faster in order in a downstream direction on a feed path and return path. CONSTITUTION:When a thing to be treated is inserted through a pair of feed rollers R2, the same is detected by an optical sensor P1 and the rollers each are turned through microcomputer control. Then when the thing to be treated passes through a pair of hot press rollers R1, a laminated film is heated and pressed against a printed matter for pressure bonding. When a matter that passing of this laminated thing through that place has been completed is detected by an optical sensor P2, the rollers each are inverted and the laminated thing is sent back to an inserted position further. In either case of a feed path and return path, the peripheral speed of the roller is made faster in order by a control device in a downstream direction which is an advancing direction of the thing to be treated. Therefore, as the laminated thing is pulled toward a downstream side always, the same is hard to be creased and jams do not occur.

Filed: 1991-08-07
Abstract: PURPOSE:To enable a synchronization discriminating circuit for spectrum dispersion demodulator to precisely discriminate synchronization regardless of the level of C/N of input signal by utilizing for synchronization discrimination the matched pulse output timing of the dispersion code catching circuit. CONSTITUTION:Input signal is treated for A/D conversion, and the correlation value between the dispersion code for modulating this input signal and the dispersion code for demodulating this input signal by dispersion code generator 15 is obtained by digital filter DMF3. Further, from the output of DMF3 a timing at which the correlation value is made to be the maximum by the maximum value detector 4 is detected, this timing is compared with the dispersion code generator initializing timing for the controller of dispersion code generator initialized by the maximum value detecting timing when catching the dispersion comparator 5 to obtain synchronization discriminating 7. As a result at a low C/N ratio of input signal, synchronization discriminating can be carried out precisely.
